  The frequency of use of connectors is extremely high. In life, we have seen connectors more or less. For professionals, the connector is a device that needs to be touched every day. In order to improve everyone's understanding of connectors, this article will explain the connectors from two aspects: 1. A brief introduction to the connectors, 2. The difference between FFC connectors and FPC connectors, and the common types of the two . 1. A brief introduction to the connector The connector refers to an electrical connector. That is, a device that connects two active devices to transmit current or signal. The connector is a component that our electronic engineering and technical personnel often contact. Its function is very simple: it builds a bridge of communication between blocked or isolated circuits in the circuit, so that the current can flow and the circuit can realize the predetermined function. Connectors are an indispensable part of electronic equipment. Observing along th...

Since entering the 5G era, mobile phones have been developing towards being thinner and more versatile. The internal integration of mobile phones is high, and the requirements for mobile phone connectors are also higher. The  FPC connector  has the characteristics of high flexibility, high flexibility, small spacing, and low height, which is well adapted to the development needs of mobile phones. Due to the advantages of FPC connectors in connection, they have become the main connection accessories in electronic devices including mobile phones. The mobile phone FPC connector has a complete production process. From pre-production to final shipment, each step needs to be rigorously executed, especially the selection of suitable modules in the test. The BTB/FPC high-current shrapnel micro-needle module has a perfect solution in the mobile phone FPC connector test. The FPC connector has a broad market development prospect, with a small and thin profile structure and a high-frequen...

Among the many connectors, have you heard of  FPC connectors  and how much do you know about them? Today in this article, Konnra connector engineers will introduce you to the basic elements of ensuring that FPC connectors are easy to transfer and reliable. Hope that Through our introduction, you can have a deeper understanding of FPC series products.   Generally speaking, the basic elements to ensure easy transfer and reliable connection of FPC connectors mainly involve three parts: substrate, adhesive, and metal foil. The specific content is as follows: I. Substrate The base material is the base material, which provides the basis for the laminate. It is a flexible polymer film that provides the main physical and electrical properties of a flexible circuit. Although the thickness of the base material is typically in the range of 1/2 mil (1 mil = 0.0254mm = 25.4  μ m) to 5 mils, thicker or thinner materials can also be used. Generally, thinner materials are s...

For FPC connectors, you should be familiar with it. It is a kind of flexible circuit board. There are many types. You know how the FPC connector can be classified. The following Konnra Electronics engineers will teach you what to use. The way to distinguish between  FPC connectors , I believe you will understand after reading. In general, the classification of FPC connectors can be distinguished according to the three ways of PCB mating, insertion force, and frame orientation. The details are as follows: First, according to the way of PCB cooperation 1. SMD-SMT: Use the pad on the board surface, then print the solder paste and temporarily attach the part foot, and then become the solder joint through the reflow furnace (Reflow). 2. Pin-inserted-DIP: Punch the PCB board, pass the connector pins through the holes on the board, and solder them. Second, according to the insertion force 1.ZIF (zero insertion force), specifically divided into front squat, rear squat, drawer. 2. Non-ZI...

There are a variety of welding methods for FPC connectors, and these welding methods are now detailed by Konnra Electronics engineers. The  FPC connector  is used for the connection of the LCD display to the drive circuit (PCB) and is currently based on a 0.5mm pitch product. The 0.3mm pitch product has also been used in large quantities. With the recent trend of LCD drivers being integrated into LCD devices, the number of pins of FPCs has been correspondingly reduced, and related products have appeared on the market. In the longer term, FPC connectors will be expected to be integrated with other mobile phone components on the frame of mobile phones or their LCD modules. Products are mainly used in various digital communication products, portable electronic products, computer peripherals, measuring instruments, automotive electronics and other fields, such as mobile phones, digital cameras, notebook computers, MID, MP3\4\5, handheld game consoles, audio systems, etc. . FPC con...

Talking about the FPC connector, I think you will not be unfamiliar, because in many fields, the use of FPC connectors will be involved. Then you know, what are the packaging methods of the FPC connector in the manufacturing process? Let the electric bee preferred electronic engineer give you a detailed description of the packaging method of the  FPC connector . Konnra Electronics engineers pointed out that in the production process of small pitch FPC, it is necessary to package to protect the coplanarity of the terminals and the positive position of the terminal arrangement, so as to reduce the quality of the FPC connector products during packaging and transportation. problem. Therefore, two types of packaging are mainly used in packaging, one is a PVC tube package, and the other is a carrier tape package. The details are as follows: First, PVC pipe packaging Among them, the PVC tube package has poor protection performance for the small pitch FPC connector, and the SMT process ...

What do you know about FPC connectors? Now that there is a flexible technology to produce FPC connectors that are favored by the market, what is the reason behind this,  Konnra Electronics engineers are here to analyze the reasons why the  FPC connectors  produced by flexible technology are popular. According to the observation of  Konnra Electronics  engineers, Samsung, LG, Intel and other large companies have all withdrawn from flexible screen-related products. Because of this phenomenon, flexible screens have entered people's field of vision, and the wearable devices that followed It is to make the demand for flexible circuit boards go forward. Therefore, the FPC connector produced by flexible technology has gradually become a hot spot in the market. According to Konnra Electronics survey data, global flexible circuit board production will reach 13.2 billion US dollars in 2016, with a compound annual growth rate of 7.5%, becoming one of the fastest growin...

        Users who often interact with FPC connectors are very knowledgeable about the structure of FPC connectors. What is the structure of the FPC connector? The following Konnra Electronics engineers will come to your FPC connector. The structural principle of this aspect.          Konnra Electronics  engineers pointed out that FPC connectors can be thinned, and to reduce the footprint of the connector, and to achieve a miniaturized, high-frequency signal transmission connector, the connector consists of four parts, respectively, the core, the tongue , terminals, soldering pieces, the following is the knowledge of these four parts;         1. The function of the FPC connector rubber core is to protect the terminal, insulation, guiding when connecting, providing the strength of the mechanism, etc. The manufacturing process of the FPC connector rubber core is generally using an injection molding process, and the ma...
